Laser Measuring Device

ABSTRACT

The tool is V shaped constructed of aluminum. A ninety degree ledge is located on the bottom side extending across the center of the tool, a scribing channel located in the center of the bottom and top, two leveling screws, four ports (screws can be moved between ports) two located on the front right and left side of the laser, and two located on the right and left side on the top of the unit, three leveling vials 5/16×⅞ one located on the front right of the laser and two located on the top, left side and right side and one (line not dot) three volt brass housed infrared optic and laser diode with attached driver 635 nm 8 mm×13 mm. It is powered by two 1.5 volt batteries encased within the unit located on the top side secured with two screws, On/Off switch located on top side.

FIELD OF THE INVENTION

This invention generally relates to a laser measuring device for finding the intersecting points and peaks in the construction field generally used by carpenters and sheetrock installers.

BACKGROUND OF THE INVENTION

Laser measuring devices are well known to the construction field, typically they are hand held or placed on a tripod, have at least one laser and at least one leveling vial. While being placed on a tripod assures stability moving it from destination to destination is quite time consuming. There is also the fact that most of these devices do not fit in the average tool belt or box.

Unfortunately, however in the field of a carpenter or sheetrock installer it is not efficient to set up a tripod for the laser every time there is a need to measure an intersecting point or a peak, nor do these devices give you a scribing channel to mark the measurement. This unit is unique due to the ledge and scribe design. It is also highly portable and extremely accurate, it may be carried in a tool belt or box it may replace traditional methods of measurement that require bulky devices and setup time.

BRIEF DESCRIPTION OF THE INVENTION

The Ledge Laser may be a vertical or horizontal laser measuring device that is specifically designed with a ninety degree ledge that may seat comfortably on any panel, that may be such as but not limited to (wood, sheet rock, tile) that has a ninety degree angle, for the purpose of locating and marking hard to measure intersecting points and peaks. The ledge on the unit may rest against the panel creating a very stable base therefore creating an environment where there may be no fluctuation in the measurement once the unit has been set, if used horizontally it may provide hands free use as it rests on top of the panel. To set the unit there are two leveling screws but not limited to just this number of screws positioned in the front of the unit but not limited to that position and two leveling vials but not limited to this number of vials which insures an accurate reading. The unit may also have the ability to check if the panel or wall are plumb by placing said screws in the holes provided in the top of the unit and adjusting according to the leveling vial on the top. The scribing channel set directly behind the laser may enable you to mark out the intersecting point or peak with a very straight line assuring accuracy. the laser being a line and not a dot can be seen around corners making marking a boxed area easy and effective. The unit is three volt but not limited to this, it has a battery compartment and is powered by two N Cell batteries but not limited to this it may be AA, AAA or any other type of battery. The size of the unit may make it very convenient to use as it may fit into almost all tool belts or boxes.

DETAILED DESCRIPTION OF THE INVENTION

As disclosed herein with regards to an exemplary embodiment, the present invention has a unique ninety degree ledge on the bottom and a scribing channel.

Referring to FIG. 2.9 the ledge across the width of the bottom of the device.

Referring to FIG. 1.1 the scribing channel. this channel may have more than one function it can be used to place an accurate mark on a stud generally 48″ or less, plumb the laser turn it on and locate where the angles and slopes are in relation to the mark, this works well in stair wells for sheetrock installation.

The Ledge Laser is a device constructed of aluminum but not limited to said material it could be constructed of plastic, rubber etc that has a 90 degree ledge located on the bottom side of the unit but not limited to this location referring to FIG. 2.9 this is how the unit may seat flatly on the panels, the design may insure stability for measuring intersecting points and peaks but not limited to just this function. The unit may be held stationary with one hand (meaning absolutely no fluctuation) while adjusting the two screws referring to FIG. 1.3 located on either side of the laser on the front, using the leveling vials located on the front referring to FIG. 1.4, 1.5 and or the top referring to FIG. 1.6 the readings may be very accurate and the easy to turn screws make it an extremely quick process. Having the scribing channel referring to FIG. 1.1 located directly behind the eye of the laser makes certain there may be an accurate level mark on the surface.

The Ledge Laser is specifically designed so that it may seat comfortably on any panel be it horizontal or vertical for the purpose of locating and marking difficult to measure intersecting points and peaks. An example would be beams across the ceiling, you need to know where to make the cuts in the panel, (1). Place the panel against the wall. (2). Place the Ledge Laser on the top of the panel. (3). Turn on the unit and level it. (4). Direct the laser to the left side of the beam use the scribing channel to make the mark. (5). Direct the laser to the right side of the beam use the scribing channel to make the mark (6). There is now an accurate spot to make the cut in the panel for the beam.
